This article explains what Local Law 84 is, how it works, andmost importantlyhow it helps you reduce energy costs and increase your propertys value.

What Is Local Law 84?

Local Law 84, part of New York Citys Greener, Greater Buildings Plan (GGBP), requires large buildings to track and report their yearly energy and water consumption. The goal is to improve building performance and reduce the citys greenhouse gas emissions.

Who Needs to Comply?

As of 2024, the law applies to:

• Residential and commercial buildings over 25,000 square feet

• Multiple buildings on the same tax lot that total over 100,000 square feet

• Condos with combined square footage of over 100,000 square feet

Building owners must submit benchmarking reports each year through ENERGY STAR Portfolio Manager, a free online tool from the U.S. EPA.

How Benchmarking Leads to Energy Savings

You might wonderhow does simply reporting energy use actually save you money?

The answer lies in awareness and action. LL84 forces building owners to examine their energy habits and identify inefficiencies. Once building performance is measured, owners can take action to improve it.

Here are the specific ways LL84 helps reduce energy costs:

1. Provides a Clear Energy Use Baseline

Benchmarking gives you a clear snapshot of your buildings energy consumption over time. By comparing your usage year over year or with similar buildings in your area, you can:

• Identify unexpected spikes in energy use

• Pinpoint inefficient systems

• Track improvements after upgrades

Example: If your energy bill suddenly rises in the winter months, LL84 data may reveal outdated heating systems or poor insulation causing heat loss.

2. Encourages Cost-Effective Upgrades

Once inefficiencies are found, you can invest in energy-saving improvements. Many of these upgradeslike LED lighting, smart thermostats, or insulation improvementspay for themselves quickly through reduced energy bills.

Data-backed decisions also make it easier to prioritize which upgrades offer the highest return on investment.

3. Increases Access to Incentives and Rebates

Benchmarking data can make your building eligible for energy efficiency programs offered by:

• Con Edison

• NYSERDA (New York State Energy Research and Development Authority)

• Federal tax incentives

These rebates often cover a large portion of upgrade costssometimes up to 70%making your path to savings even easier.

4. Improves Tenant Satisfaction and Retention

Todays tenants want eco-friendly and energy-efficient buildings. A well-benchmarked, energy-optimized building leads to:

• Lower utility bills for tenants

• Better indoor air quality

• Consistent heating and cooling performance

This makes tenants more likely to renew leases, reducing costly vacancies.

5. Boosts Property Value and Marketability

Properties that comply with LL84and take energy performance seriouslystand out in NYCs competitive real estate market. Energy-efficient buildings:

• Sell faster

• Attract higher rents

• Retain value longer

Having solid benchmarking reports and a high ENERGY STAR score can be a selling point for buyers and investors.

6. Avoids Costly Fines

Compliance with LL84 is mandatory, and failing to file benchmarking reports can lead to fines of $500 per quarter, up to $2,000 per year. Staying compliant saves you from unnecessary penalties that eat into your operating budget.

7. Supports Long-Term Local Law 97 Goals

LL84 is more than just a standalone regulationits a foundational step for complying with Local Law 97, which sets strict greenhouse gas emissions limits starting in 2024. Benchmarking helps building owners:

• Track emissions

• Set reduction goals

• Avoid future carbon penalties under LL97 NYC

In short, LL84 prepares you for the future of sustainable building management.
